I love me some Tube Lights! I received an early sample of Lume Cube's Tube Light XL and I'm very impressed. Yes, the light quality is great. They claim a CRI of 96+ and I believe it. The controls are easy to understand. I got a full understanding of how to use the light in all of 30 seconds. The power bank is something I will definitely be using and I no longer need to carry a separate power bank. Favorite feature? Probably the color picker in the app! I work with a lot of brands, and now i'm able to take a photo of the brand's colors and my lighting will follow suit. Very cool. I haven't been this impressed by a light in a very long time! Highly recommend.
